Egg And Curd Recipe: Crispy Wonton Cups With Spiced Yolk Filling

This egg and curd recipe delivers crispy wonton cups stuffed with a rich, spiced yolk filling that's impossible to resist. The secret lies in the delicate balance between tender wonton wrappers and the perfectly set custard center, creating a bite that's both satisfying and elegant. I developed this recipe after years of experimenting with Asian-inspired breakfast dishes, and it consistently earns rave reviews at brunch gatherings.

The foundation begins with store-bought wonton wrappers, which we transform into crispy cups through a simple baking technique. Inside, a custard made from eggs, curd (or Greek yogurt), and warm spices creates a velvety filling that sets just enough to hold its shape. The combination of textures—crispy exterior, creamy interior—makes each bite a revelation, while the subtle warmth of cardamom and cinnamon adds depth without overpowering.

What makes this dish truly special is its versatility—serve these cups as a standalone appetizer, pair them with a fresh cucumber salad for balance, or use them as a sophisticated breakfast topping for avocado toast. The recipe yields about 24 cups, perfect for sharing or meal prepping ahead. The key to success is patience during the custard preparation and ensuring even baking for that perfect golden crust.

Once you try these crispy wonton cups, you'll understand why they've become a brunch favorite. The technique is approachable yet impressive, and the results are undeniably restaurant-quality. Whether you're hosting a weekend brunch or simply craving something special for breakfast, this recipe delivers on both flavor and presentation. Let's get started on creating these addictive little bites.

Ingredients for egg and curd

Twenty-four crispy wonton cups await, each with a velvety spiced yolk center.

The wonton wrappers form the crispy foundation—Martini brand works best for consistent shape, but any store-bought variety suffices. Look for wrappers with minimal folds to ensure even baking. For the custard filling, full-fat Greek yogurt creates the ideal creamy texture; low-fat versions may yield a less luxurious result. Cardamom and cinnamon should be freshly ground for maximum aromatic impact—Penzeys Spices offers excellent pre-ground options if you lack a mortar and pestle. The butter used for brushing must be melted just until fluid to ensure even distribution without sogginess.

No Greek yogurt? Full-fat sour cream or crème fraîche work as direct substitutes, though texture may vary slightly. Substituting ground spices? Ceylon cinnamon is gentler than cassia, while green cardamom pods can be toasted and ground for a more complex profile. For a tangier filling, add 1 tsp lemon juice to the custard mixture. The cucumber garnish can be swapped for radish slices if preferred, though cucumber's crispness complements the dish beautifully. Avocado should be ripe but firm—Hass variety holds shape best when sliced.

Store unbaked wonton cups in an airtight container between parchment-lined layers for up to 2 days before baking. Fully assembled cups can be refrigerated for 4 hours maximum prior to baking to prevent over-softening. Once baked, these cups reheat beautifully in a 350°F oven for 5-7 minutes. For meal prep, bake half the batch immediately and freeze the remaining cups on a parchment-lined tray before transferring to a sealed bag—reheat directly from frozen at 375°F for 10-12 minutes. Garnishes should always be added fresh post-baking to maintain vibrant presentation.

Step-by-step instructions for crispy wonton cups with spiced yolk filling

Transform delicate wonton wrappers into crispy cups with a rich, spiced yolk filling—here's how to achieve perfect texture every time.

In a medium bowl, whisk together the 4 whole large eggs until the yolks and whites are fully combined and the mixture is uniform in color. This ensures even cooking and a silky texture in the filling. In a separate small bowl, combine the 0.75 cup Greek yogurt (or curd), 0.5 teaspoon ground cardamom, 0.5 teaspoon ground cinnamon, and 0.25 teaspoon salt. Whisk until the spices are fully dissolved and no dry pockets remain.

Gradually fold the spiced yogurt mixture into the egg mixture, alternating between the two bowls to maintain an even distribution. The final filling should be smooth, slightly thickened, and fragrant with warm spice notes. Cover the bowl and refrigerate for at least 15 minutes—this resting period allows the flavors to meld and the mixture to thicken slightly, which prevents leaks during baking.

Preheat your oven to 375°F and line two baking sheets with parchment paper. Using a round cookie cutter or the rim of a small glass, cut 24 circles from the wonton wrappers—each should be about 2 inches in diameter. Brush the edges of each circle lightly with 1 tablespoon melted unsalted butter, then gently press them into muffin cup molds or small ramekins, forming cups with slightly fluted edges.

Carefully spoon 1 teaspoon of the spiced yolk mixture into each wonton cup, filling them about ¾ full. The filling should mound slightly above the cup's edge—this ensures a generous bite while preventing overflow during baking. Place the assembled cups on the prepared baking sheets, spacing them 1 inch apart for even browning.

Bake the wonton cups for 12-15 minutes until the edges are deep golden brown and the filling has just begun to set. You'll know they're ready when the cups lift easily from the baking sheet and the filling holds its shape when gently shaken. Avoid overbaking—the filling should still have a slight jiggle in the center, as it will continue to firm up as it cools.

Remove the cups from the oven and let them cool on the baking sheet for 5 minutes. This brief resting period allows the filling to fully set while maintaining its creamy texture. If the filling appears too soft after cooling, return the cups to the oven for 1-2 additional minutes to firm them up slightly.

While the cups are still warm, brush the tops lightly with 1 tablespoon olive oil to enhance their crispiness. Arrange thinly sliced cucumber, ripened avocado slices, and chopped fresh mint on a platter. Transfer the wonton cups to the platter and garnish each one with a small piece of cucumber, avocado, and a sprinkle of mint. Finish with a pinch of 1 teaspoon lemon zest for a bright, aromatic contrast.

Serve the crispy wonton cups immediately—the contrast between the delicate, spiced filling and the crispy wonton shells is best enjoyed when everything is at its peak texture. The warm spice notes from the cardamom and cinnamon will complement the creamy yolk, while the fresh garnishes add a refreshing crunch and visual appeal.

Pro cooking tips for this recipe

Perfect Custard Texture

The secret to a velvety filling lies in the 15-minute refrigeration of your egg-yogurt mixture. This resting period allows the proteins to relax and thicken slightly, preventing leaks during baking. I like to whisk the eggs vigorously first—1 minute with a fork, then 30 seconds with a hand mixer—to create tiny air pockets that make the filling lighter. For extra insurance, add 1 teaspoon cornstarch to the yogurt mixture if you're concerned about runniness. 🥚

Wonton Wrapper Prep

Use Martini brand wonton wrappers for consistent shape and thickness—they hold their structure better during baking. Before cutting circles, brush the wrappers lightly with melted butter (not oil) to prevent sticking and add richness. I cut my circles using a 2-inch round cookie cutter, but a glass rim works just as well. Press the edges firmly into muffin tins to create sturdy cups that won't collapse during baking. 🥟

Baking Temperature Control

Bake at 375°F for 12-15 minutes—any hotter and the wrappers burn before the filling sets. Rotate the baking sheets halfway through for even browning. The filling should look just set but still slightly jiggly in the center. If you're unsure, test one cup by gently shaking it: the filling should hold its shape without spilling. 🌡️

Garnish Timing Matters

Add fresh garnishes right before serving—the cucumber stays crispest when sliced last, and the avocado holds its texture better when added warm. I like to sprinkle lemon zest over everything just before plating to brighten the warm spices. For an extra touch, drizzle with 1 teaspoon honey mixed with a pinch of salt for a sweet-savory contrast. 🍋

Make-Ahead Strategy

Assemble unbaked cups up to 4 hours ahead and refrigerate. Bake straight from the fridge—no need to bring to room temperature. For freezing, bake half the batch, let cool completely, then store in an airtight container for up to 1 month. Reheat frozen cups at 375°F for 10-12 minutes until warmed through. The texture remains perfect when reheated properly. ❄️

Spice Adjustments

If you love warmth, add ¼ teaspoon freshly grated ginger or pinch of cayenne to the yogurt mixture. For floral notes, swap ¼ teaspoon cardamom for rose water (just 2 drops). I find Ceylon cinnamon adds a sweeter, more delicate flavor than cassia. Always taste the spiced yogurt mixture before combining with eggs—this ensures perfect balance in every bite. 🌿
